    Discrete Ritz Method

    Zhao Jing1,*

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.25, No.1, pp. 1-1, 2023, DOI:10.32604/icces.2023.09832

    Abstract Ritz method runs into difficulties when dealing with complex geometry domain due to the difficulty of constructing a global trial function to approximate structural deformation and the complexity of integration. In this paper, a novel numerical approach, discrete Ritz method (DRM), is proposed for the free vibration analysis of arbitrarily shaped plates with arbitrary cutouts. Legendre polynomials are adopted to generate the admissible function. DRM transforms the complex geometry domain into a system of rectangular domain with variable stiffness. Standard energy functionals and computation procedures are established for arbitrarily shaped plates. Then, in terms of… More >

    Measuring the Tensile Strength Degradations of Mineral Grain Interfaces (MGIs) in the Granite After Thermo-hydro-mechanical (THM) Coupling

    Mengyi Li1, Zhijun Wu1,*

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.25, No.1, pp. 1-2, 2023, DOI:10.32604/icces.2023.09829

    Abstract Buried in depth for decades of years, granite in the deep geological repository will be subjected to extremely complex effects of thermo-hydro-mechanical (THM) treatment, and the tensile strengths of mineral grain interfaces (MGIs) are inevitably impacted by the THM treatment [1, 2]. Originated by the failure modes of granite after THM treatment, the tensile strength of MGI plays an important role in determining the macro mechanical properties of THM-treated granite [3, 4]. However, the accurate characterization of the tensile strength degradations of MGIs with THM treatment is still lacking. In this study, the varied tensile… More >

    A Numerical Method of Granular Flow for Hazard Prediction Based on Depth-Integrated Model and High-Resolution Algorithm

    Wangxin Yu1,*, XiaoLiang Wang1, Qingquan Liu1, Huaning Wang2

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.25, No.1, pp. 1-1, 2023, DOI:10.32604/icces.2023.09825

    Abstract Landslide, debris flow and other large-scale natural disasters have a great threat to human life and property safety. The accuracy of prediction and calculation of large-scale disasters still needs great improvement, so as the study of prevention and interaction. In this paper, the depth-integrated shallow water flow model is adopted, and the numerical method of Kurganov developed in recent years is used to develop a highresolution algorithm which can capture shock waves and satisfy the hydrodynamic conditions. In order to make it adapt to the granular flow, appropriate adjustment is made distinct from the original… More >

    Three-Dimensional Numerical Simulation of Large-Scale LandslideGenerated Surging Waves with a GPU‒Accelerated Soil‒Water Coupled SPH Model

    Can Huang1,*, Xiaoliang Wang1, Qingquan Liu1, Huaning Wang2

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.25, No.1, pp. 1-1, 2023, DOI:10.32604/icces.2023.09824

    Abstract Soil‒water coupling is an important process in landslide-generated impulse waves (LGIW) problems, accompanied by large deformation of soil, strong interface coupling and three-dimensional effect. A meshless particle method, smooth particle hydrodynamics (SPH) has great advantages in dealing with complex interface and multiphase coupling problems. This study presents an improved soil‒water coupled model to simulate LGIW problems based on an open source code DualSPHysics (v4.0). Aiming to solve the low efficiency problem in modeling real large-scale LGIW problems, graphics processing unit (GPU) acceleration technology is implemented into this code. An experimental example, subaerial landslidegenerated water waves,… More >

    Interfacial Delamination in High-Temperature Coatings with Segmented Microstructures

    Biao Li1,*

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.25, No.1, pp. 1-2, 2023, DOI:10.32604/icces.2023.09818

    Abstract High-temperature coatings are extensively used in aircraft engines and industrial gas turbines to protect hot-section components from harsh operating environments [1]. Representative high-temperature coatings include thermal barrier coatings and environmental barrier coatings, which are applied to substrates made of superalloy and ceramic matrix composites, respectively. The durability of the coatings is of significant importance for the structural integrity of the components [2-4]. A segmented microstructure was widely used to improve the coatings' durability. A network of through-thickness vertical cracks is introduced into the outer layer of the coatings, which increases the compliance of the coatings… More >

    Flexoelectric Polar Patterns in Wrinkled Thin Films

    Hongxing Shang1,*, Xu Liang1, Shengping Shen1

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.25, No.1, pp. 1-1, 2023, DOI:10.32604/icces.2023.09816

    Abstract Flexoelectricity is the coupling effect of polarization and strain gradients, which tends to be more pronounced in thin films owing to size dependency. When subjected to in-plane compression, a filmsubstrate system will form complex wrinkle morphologies along with large-area and tunable strain gradients. The wrinkle-induced strain gradients can locally break the inversion symmetry of dielectrics and thus introduce flexoelectric polarization. Here, an electromechanical coupling model is developed to theoretically deal with flexoelectric polar patterns in wrinkled thin films. By analyzing the energy competition of elastic potential and electrostatic energy, the amplitude, wavelength, and critical strain… More >

    Data-Driven Enhanced Combined Finite-Discrete Element Method for Simulating Rock Failure Progress

    Ruifeng Zhao1, Zhijun Wu1,*

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.25, No.1, pp. 1-2, 2023, DOI:10.32604/icces.2023.09814

    Abstract The combined finite-discrete element method (FDEM) can effectively simulate the continuousdiscontinuous failure process of rocks, and is now widely adopted to investigate the issues related to rock mechanics and engineering. The conventional FDEM requires pre-defines constitutive models to calculate the element stress from element deformations [1]. However, the constitutive model used in conventional FDEM is obtained by empirical fitting of rock mechanics test data, and large amount of rock physical and mechanical information present in the test data, such as the nonlinear properties of rock presented in the initial compaction stage, are lost in the… More >

    The Body Deformation and Energy Transfer of Undulatory Propulsion in Fish Swimming

    Mengfan Xu1, Yongliang Yu1,*

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.25, No.1, pp. 1-2, 2023, DOI:10.32604/icces.2023.09812

    Abstract During the steady swimming of carangiform or anguilliform swimmers, the fish body shows significant fluctuation characteristics. The formation of waving body is not only related to the driving force of fish muscle, but also to the material properties of fish body and fluid forces. In fluid mechanics, the propulsive force of fish body is closely related to reverse Kármán vortex street. However, there is still a lack of comprehensive understanding of the work done by the driving force, the formation of the fluctuation and propulsion of the fish. Based on the kinematic chain integration framework,… More >

    Mechanics of Multiphase Media Under Hyper-gravity Conditions

    Guannan Wang1,*, Yulin Huang1, Lei Wang1, Weijian Wang1

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.25, No.1, pp. 1-1, 2023, DOI:10.32604/icces.2023.09806

    Abstract With the energetic development of aerospace and aviation industries of our country, it is a critical and onerous mission to protect the life and health of astronauts and aviators. It is already demonstrated in the real flight or centrifuge test that several living organisms would suffer large deformations, instability or even damages under extreme hyper-gravity environment. To overcome the shortcomings from those direct experimental measurements in the literature, the present project will establish a theoretical framework to investigate the deformation and buckling of composite materials or structures systems under hyper-gravity effect. In the meantime, a… More >
